FINISHENG PLATE.

Application filed September 12, 1924. Serial No. 737,341.

This invention relates to finishing plates that are used for concealing openings in floors, walls and cealings through which pipes pass, and. it has to do more particularly with the sectional type of finishing plate that is designed to be contracted about a pipe after the pipe is installed, in contradistinotion to the one-piece type consisting of an annulus that hasto be placed in position during installation.

The fundamental purposes of my invention are to provide a'sectional finishing plate that is neat and attractive in appearance and which is very simple and economical of manufacture.

By virtue of my invention, sectional finishing plates may be cheaply produced for special conditions. The internal diameter of a plate, for example, may be easily varied with respect to' the external diameter thereof, as circumstances require.

The present preferred embodiment of the invention is illustrated in the accompanying drawing wherein Fig. 1 is a perspective view showing the finishing plate surrounding a pipe and applied to the surface through which the pipe passes; Fig. 2 is an inside face view of the plate in closed condition; Fig. 8 is a similar view showing the plate open so that it may be engaged about a pipe; Fig. 4: is a sectional detail on the line H of Fig. 2; and Fig. 5 is a sectional detail on the line 55 of the same view. The finishing plate, which is shown as annular, is formed of two halves or sections 1 and'2. l/Vhere the sections meet on one side they are permanently connected together by a sliding hinge connection consisting of a metal strap 8 that is spot-welded or otherwise secured to the section designated 1, and overlies the adjacent end of section 2. The strap 3, where it overlies section 2, is provided with a slot 4': through which a screw 5, carried by section 2, passes. The screw is threaded through a nut 6, preferably formed of a piece of sheet metal similar to that from which the strap 3 is made, and one edge of the nut is turned over, as indicated at 7 for engagement with the edge of the strap 3, to hold the nut against turning.

To the opposite ends of the respective sec tions 1 and 2 are connected, as by spot-welding, a clip 8 and a tongue 9. The end of the clip 8 adjacent the straight edge of'the section 1 is spaced from the adjacent surface of said section a distance substantially equal to the thickness of the tongue 9 so that the free end of the tongue may engage between the clip and the section 1 when the two sections are brought together. A. screw 10 passes through an aperture in the section 1- and is threaded through the clip 8, and the tongue 9- is notched at 11 for the reception of said screw when the parts are in closed position. ,Vtlhen the sections are moved toward and from each other, the section 2 s i es alone th s ap 3 in a smal e -r di y uuderstood from the illustrations of Figs. 2 and 3; and when the parts are together, as when the plate is placed about a pipe 12, the screws 5 and 10 may be tightened to bind the parts in closed condition, the strap 3 being clamped between section 2 and the nut 6, and the tongue 9 between section 1 and the clip 8.

By reason of the fact that the fastening means are made separate from the sections of the plate, and secured thereto during the process of manufacture, the plates themselves may be stamped by means of circular dies and then split into halves or sections 1 and 2. In the production of the plates a die of one size may be employed for stamping out disks of a diameter which determines the external diameter of the plate, and a similar but smaller die may be used for punching the centers from the disks. The dies may be of any relative proportions to effect plates of the desired width. After the plates are halved, the connecting means may be applied. This simple and cheap method of manufacture is due to the fact that there are no tongue or extensions or other irre ularities necessary on the sections of the plate to provide the hinge and latch connections between them. The method, thus described, is so obvious as to make unnecessary specific illustration thereof.

Having thus described my invention, what I claim is:

1. An annular finishing plate comprised of half sections which meet on a line passing diametrically through said plate, a strap secured to the underneath side of one end of one section and underlying the adjacent end of the other section, the underlying portion of said strap being longitudinally slotted, a screw carried by the last men tioned section and passing through said slot,

a nut applied to said screw beyond said strap and having one of its edges formed for cooperation with the edge oi the strap to prevent the nut from turning with respect thereto, and means for connecting together the opposite ends of the sections.

2. An annular finishing plate comprising halt sections which meet on a line passing substantially diametrically through the plate, means hingedly and slidably connecting the ends of said sections together at one side of the plate, a clip secured to the underneath side of the tree end of one of the sections and having a part spaced therefrom, a screw carried by the section and threaded through said part of the clip, and a biturcated tongue carried by the underneath side of the tree end of the other section and adapted to enter between the clip and said other section and to receive within its bifurcation the aforesaid screw.

3. An annular finishing plate comprised of half sections which meet on a line passing diametrically through said plate, a member rigidly secured to the underneath side ii,

of one end of one section and mulerlying the adjacent end of the other section, the underlying portion of said member having a longitudinal slot at substantially right angles to the atoresaid line, a pivot carried by said other section and engaged through said slot, a clip secured to the underneath side of the free end of one of the sections and having a part spaced therel'rom, a screw carried by the section and threaded through said part of the clip, and a bifurcated tongue carried by the underneath side of the tree end of the other section and adapted to enter between the clip and said other section and to receive Within its bifurcation the aforesaid screw, the axis oi said bifurcation being substantially parallel to the axis of the aforesaid slot.

In testimony whereof, I hereunto allix my signature.
